mounted a further lever 31. This lever 31 is provided with a projectionagainst which there bears the end of a rod 40 provided with teeth 39(Figs. 10, 11). The other end of the rod 40 is provided with a head 4|(Figs. 1, 2).

The rod 3 is under the action of a spring 43 which tends to move the rodtowards the right (Figs. 1-4, 10, 11) To the rod 3 isalso hinged a lever44 (Figs. 10, 11) which in turn is connected to one end of adouble-armed lever 45. The latter is mounted on a plate 46, rigidlyconnected to the carriage R. The other end of the lever 45 carries aroller 41. On the plate 46 is also mounted a bell crank lever 48 (Fig.11) of which one end carries a roller 49, whilst the other end isconnected to a pull rod 50.

Laterally of the table T is located a rail 52 (Figs. 1, 2,3) carrying arack 53. On this rack 53 is movably mounted a slide 54 (Figs. 3, 5, 6,7). With a slot of the latter there engages a pawl 55 which is held inthe position shown in Fig. 5 by a spring 56. A key 51 is held in theraised position by a projection 58 of the pawl 55 (Fig. 5). A stopmember 6|, secured by screws 60, is mounted movably on the slide 54, themember 6| being forced into the position shown by the springs 62. In theslide 54 there is also mounted a spring actuated projection 63' (Figs.3, 7) which is in connection with one end of a doublearmed lever 64. Thelatter carries a pin 65.

The key 51 projects into the path of a lever 61 (Figs. 1, 2, 15, 16)hinged to a plate 68. The latter is secured at the bottom to the slideS, provided with the writing keys and transversely movable in thecarriage R. On the same plate 68 there is also rotatably mounted an arm69 (Figs. 1, 2, 13, 14) which at one end has an arm 78 and at the otherend a bent portion H.

To the rack 53 there is pivotally connected by means of links 12 (Figs.3, 5) a rod '13 which extends parallel to the rack 53 and at the frontis provided with a head 14. The rod 13 is held in the position shown inFig.2 bya spring 15.

The method of operation is as follows:

The rest position of the writing machine is shown in Fig. 2. The sheet Bto be written upon, for example the journal sheet or the day totalsheet, and over this the account sheet, 'the monthly account and soforth with the carbon paper and so forth, is placed on the table andclamped in the usual manner. Pressure is then applied to the head 14 ofthe rod 13 whereby the latter is rocked outwardly and moves away fromthe rack 53 (Fig. 9). Consequently the lever 24 bearing against the rod13 makes a rocking move-. ment. The pull rod 23 rocks the bell cranklever 22 against the action of its spring until the pro-' jection 2|releases the projection 20 of the lever IS. The latter, under the actionof its spring I8, snaps to the left (Figs. 3, 9) and israisedsimultaneously as a projection thereof 'runs over the surface 'l8of the bearing head I1. A pin 80 of a rod 8| is thus caused to pass intothe notch 19 of the lever I6; the rod 8| is thus drawn to the left(Figs. 3 and 9). .The other end of the rod 8| is connected to the lever21. The lever 21 is rocked into the position shown in Fig. 9 and thusmoves the shaft 29 to the right, so that the pulley 3B is engaged andthe carriage R moves forwardly with the slide S (Fig. 2). At the sametime the lever l6 has also rocked the lever 4 with the roller 2. Theslide 54 has previously been set, in the exact position relatively tothe sheet B, on. the rack 53. The carriage R moves forwardlyuntil itsstop member 25 (Figs. 2, 9)

strikes against the projection 83 of the stop member 6|, the springsabsorbing the shock. The projection 63, which has been forced back bythe stop member 25, again projects from the slide 54 and engages behindthe stop member 25. 5 The carriage R is held immovably. At the same timethe roller |2 has run on to the cam surface 84 of the stop member 6!,whereby the lever l4 has drawn the lever 6 back into its rest position(Fig. 3). As a result also the rod 8|, the lever 21 and shaft 29 havebeen. returned into their original position, and the pulley or gear 30is disengaged. The slide S is exactly at the line of the sheet B to bewritten upon. In order to advance the carriage when writing a fresh linethe slide S is moved to the left by the known means and in the knownmanner. The lever 61 passes the key 51 and depresses it for a shorttime. The pawl 55 is thus rocked (Fig. 15) and is disengaged from theteeth of the rack 53 in order to engage 20 immediately with the nexttooth as in the meantime the carriage R has been advanced automatically.

When the slide S has reached the end of the line the end 10 of the, arm69 strikes against a previously adjusted stop 86 (Fig. 10) provided onthe writing machine and is depressed. As a result the part H of the arm69 engages with the teeth of the rod 48 and moves the latter to theright against the projection 38 of the lever 31 which in turn rocks thelever 35. The latter by means of its projection 36 disengages the plate34, against the action of its spring, from the V notch of the extension3'. The rod 3 and the extension 3 are immediately moved to the right bythe spring 43 (Fig. 2). The actuating member 5, provided at the otherend of the rod 3, moves in the slot I0 and in the cam track 1 in such amanner that the projection 9 engages with the pin 81 of the lever 21 androcks this into the position indicated by II (Fig. 3) whilstsimultaneously moving the shaft 29 to the left. The gear or pulley 38 isengaged for reverse movement and the carriage R again moves rearwardlyinto the position shown in Fig. 2. The stop 25 of the carriage, whichhas been held locked between the parts 63 and 83, is releasedsimultaneously in that during the movement of the shaft 29 to the leftthe roller 93 keyed thereto abutted against the pin and rocked the lever64. The projection .63 was thus retracted.

At the rear of the table Tare provided two stops 9|, 92. The roller 49first runs on to the stop 9| and by means of pull rod 5|] actuates aknown release device which releases the slide S, which then moves to theleft up to a stop. As soon as the roller 41 of lever 45 comes intocontact with the stop 92 the rod3 is again moved into its rest positionshown in Figs. 1-4, 10, 11 by means of the levers 45 and 44. At the same60 time the lever 2'! is rocked into its mid position (Fig. 3) thusimmediately disengaging the gear 36. The writing machine is thus againin its starting position.

By pressing the head 4| of the rod 40 pro- 5 vision is made for allowingthe carriage R to move rearwardly at any time independently as towhether the slide S has reached its right hand end position.

When the carriage has reached its rear position the sheets (accountsheets, copies and eventually also the journal sheet) can be exchanged.
